A new pyrochlore oxide $\mathrm{C}{\mathrm{d}}_{2}\mathrm{I}{\mathrm{r}}_{2}{\mathrm{O}}_{7}$ with an $\mathrm{I}{\mathrm{r}}^{5+}$ charge state was prepared by high-pressure techniques. Although strong spin-orbit coupling (SOC) dominates the electronic states in most iridates so that a SOC-Mott sta...
